Below  are  two  examples  of  vehicle  framing  with  an  ANPR  camera.  The 
first  is  zoomed  in  close  such  that  the  vehicle  width  fills  the  image  and 
ensures  the  plate  will  be  large  enough  to  be  read  (the  plate  has  been 
pixelated in this image). The second image is wrongly viewing the rear of 
the vehicle and needs to be zoomed in closer before the plate will be read.

Finally,  here  is  an  example  of  a 
colour  overview  image  taken  by 
the  dual  version  of  the  camera. 
Remember  that  when  using  these 
cameras  in  conjunction  with  an 
ANPR  processor,  the  overview 
image will be recorded a fraction of 
a  second  after  the  plate  is  read 
and  will  therefore  need  to  be 
zoomed  out  sufficiently  to  ensure 
the  vehicle  is  recorded  even  when 
travelling at high speed.
